I bought one of these OLDS o-l-d GG marching contra's awhile back and parted it out. (The bell and bow are the same as the BBb Olds O-99 and Reynold TB-10.) I used the rotary valve (off of that triggered slide) to add a 5th rotor to a 4-rotor helicon. (The bore of this OLDS rotor is fairly small, and I was able to fit the rotor smoothly into the bore of the helicon in the lower mouthpipe area.)
Here's the point of the post:
My "OLDS" rotor casing has no cap. If any one has one of these instruments in "junk" condition in a "tuba graveyard", etc., I'd like to buy the rotary valve CAP...say $20...???...to make it barely worth someone's trouble???
Thanks,
Joe
